If the number of bacteria in a colony triples every 60 minutes and the population is currently 2,000 bacteria, what will the pop
lora16 [44]
It's exponential. And you will triple the size every 60 minutes in 240 minutes, so triples 4 times. 2000 times 3 is 6000. 6000 times 3 is 18000. 18000 times 3 is 54000. 54000 times 3 is 162000 so D is the answer.

The current population of Fun City is 21000 people. If the population of the city will double every 51 years then the population
Arisa [49]

Answer:

The population of Fun City after 171 years would be 214563.

Step-by-step explanation:

The statement depicts a case of exponential growth, whose model is described below:

p(t) = p_{o}\cdot r^{\frac{t}{T} } (1)

Where:

p_{o} - Initial population, no unit.

p(t) - Current population, no unit.

r - Growth rate, no unit.

t - Time, in years.

T - Growth period, in years.

If we know that p_{o} = 21000, r = 2, t = 171\,yr and T = 51\,yr, then the population of the city after 171 years is:

p(t) = 21000\cdot 2^{\frac{171}{51} }

p(t) = 214563

The population of Fun City after 171 years would be 214563.
